Julie and Gabriel had a total of 189 marbles. Gabriel had 2 times as many marbles as Julie.
- How many marbles did Julie have?
- How many marbles did Gabriel have?
(a)
Number of marbles that Julie had = 1 u
Number of marbles that Gabriel had = 2 u
Total number of marbles
= 2 u + 1 u
= 3 u
3 u = 189
1 u = 189 ÷ 3 = 63
Number of marbles that Julie had
= 1 u
= 63
(b)
Number of marbles that Gabriel had
= 2 u
= 2 x 63
= 126
Answer(s): (a) 63; (b) 126
